TLDR recap:

The mother of all darkness may have been destroyed in body, but her spirit still lives and has taken control of the Harlequin, the most feared, respected, and skilled group of spies and assassins ever trained.  With assistance from these vampire boogeymen, Mommy Dearest is gunning for Anita, to possess her body and control her abilities.  The Harlequin have laid a clever trap for Anita, separated from her support animals and sweeties, and will stop at nothing to acquire her for their master.  With only Edward and her own preternatural skills to protect her, will Anita survive Seattle or will Mommy Dearest win at long last?
